Ok i have installed a ASUS external usb high speed burner .
Its running on low speed usb along with a low speed usb hub.
thing is if i hot swop anything in the hub my machine reboots.
Its ok if remove burner hot swops fine.
I don't know how this works really, but trying to figure out somehting, maybe u need an uprated power supply. It could be that the usb devices are drawing so much current that when u disconnect one, u get a power surge which causes the machine to reboot. Even tho ur running a burner which comes with its own power supply, it still makes me wonder. are u running any other usb devices?
